Which term describes matching sides of similar figures?

• Corresponding Sides

• Corresponding Angles

• Scale Factor

Which side length corresponds with EF?

• ML

• LM

• OL

• EH

_______ polygons have the same shape but not necessarily the same size.

If two triangles are similar, what can you say about their corresponding sides?

• Their corresponding sides are equal.

• Their corresponding sides are parallel.

• Their corresponding sides are perpendicular.

• Their corresponding sides are proportional.

Are these figures similar?

• YES

• NO

Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because they have the same shape and the same angles
• No, the ratio of corresponding sides are not equal 
• Yes, same shape
• No, different sizes

Which three things are true about similar figures?

• Corresponding sides are proportional.

• Same size.

• Corresponding angles are congruent.

• Same shape.

Similarity

• when shapes have the same side lengths

• when two figures are the same shape and have proportional sides and congruent angles, but not always the same size

• when we plot on coordinate plane
